Patent EP-0579321-A1 (EP)
Inventor: WALLAEYS BART
IPC: C08J9/00
Filed: 1993-07-08
Abstract: The invention relates to a process for producing a mainly closed cell phenolic foam by curing a foam system comprising at least a phenolic resin and a blowing agent. This curing is effected in the presence of an either or not alkylated morpholine which is fluorated whether completely or not and which corresponds to the following general structural formula : 
 
 
 
        C n  H x  F y  NO 
 
 
 
wherein : 
   n ≧ 4 
   x = 2n + 1 - y 
   y = 2n + 1 - x. 
     In this way, it is possible to obtain a phenolic foam having good insulation properties even if use is made of a blowing agent which is substantially free of CFC's or if the foam temperature is allowed to rise during the curing upto above 85°C to obtain a better curing.

Abstract: A circuit for generating a linear-feedback-shift-register sequence in accordance with a variable characteristic polynomial has multiple stages (102) each including a latch (104), an exclusive-OR gate (108) and a multiplexer (106) for coupling to the input of the latch either the output signal from the exclusive-OR gate or the signal from the preceding stage's latch. The exclusive-OR gate receives as inputs the signal from the preceding stage's latch and an output signal from the complete circuit. 
     The multiplexers are controlled to select which exclusive-OR gates are coupled to their associated latches in accordance with the characteristic polynomial of the desired shift register sequence to be generated.

IPC: H01J37/305
Filed: 1993-06-14
Abstract: A method for optimally scanning, for example, a surface of one or more silicon-on-insulator (SOI) semiconductor wafers  10  consists of a spiral type scan technique. The spiral type scan can maintain a path pattern  30  that encompasses the surface diameter of a single SOI wafer  10 . The spiral type scan can also maintain a path pattern  30  that encompasses the surface diameters of several SOI wafers  10 . The path pattern  30  of the spiral type scan does not include any abrupt redirectional changes. Thus, the machinery controlling the path pattern  30  of the spiral type scan does not undergo unnecessary mechanical stresses. Furthermore, when using, the spiral type scan in a chemical etching process of one or more SOI wafers  10  and the etch rate of a chemical etching probe  18  is modulated, the mechanical stresses are further reduced and there are minimal depreciative etching problems.

Abstract: The variations in operating conditions occurring in a biological filter tower for exhaust air purification are compensated for by addition of water which is loaded with material degradable in the biological tower (1). The constant operating conditions permit a continuous fault-free long-term operation, in which the operating conditions can also be adjusted according to long-term variations in the composition of the exhaust air. An accumulation of dissolved materials, in particular of salts, can be prevented by prompt emptying of the settling tank (5) with partial exchange of the process water. <IMAGE>

Abstract: De nombreux commutateurs de télécommunication fonctionnent selon un mode à double plan afin de présenter une meilleure fiabilité et de meilleures possibilités de maintenance. En ce qui concerne des commutateurs à mode de transfert asynchrone (MTA), il s'est avéré difficile de fusionner des cellules émergeant de deux plans identiques en raison de la nature asynchrone de la transmission. Un filtre de fusionnement de plan de MTA est décrit. Le filtre contient une mémoire servant à mémoriser la première cellule d'une paire de cellules identiques soumises au contrôle d'un élément de commande de filtre. L'élément de commande de filtre surveille les en-têtes des cellules et envoie un signal de validation à la mémoire pour la mémorisation d'une cellule lorsqu'aucune cellule identique n'est en mémoire.

Abstract: This invention consists of methods of simulating voice conversations with talking animated characters (17, 18) on a television or video screen (11). The animated characters (17, 18) talk to each other and to humans (10, 12). Each human holds a light-weight controller (47, 48) that has push buttons (14) next to a display of variable phrases or sentences (13) for each human's side of the dialog. This dialog includes alternative words (13, 26) for a human player to say to a character or for a character to say (15, 16, 20, 23, 27) or actions (Figs. 3, 7, 10) for a character to do. A human (10, 12) responds to what a character (17, 18) says or does by pressing a button (14) next to a selected phrase. An animated character then vocally responds (15 in Fig. 1) to the selected phrase as if it had been spoken by a human or as if it were the character's own words. Each scene (64) branches to subsequent scenes (65, 66, 67) and within each scene there are several branching dialog sequences (60, 61, 62, 69, 63, 68).

Abstract: A method for clear track signalling is disclosed in which axle count pulses which are acquired at counting points of a route area which comprises several sections of track are fed to a computer and stored thereby for each counting point in a direction-related fashion, in which method clear track signalling occurs for a track section if the same counter state is stored for the counting points which bound the track section and in which method correction of a counter state is performed when the counter states stored for the next two counting points in the direction of travel are the same and higher than the counter state to be corrected or when the counter states which are stored for the two directly succeeding counting points in the direction of travel are the same and lower than the counter state to be corrected. The correction takes place by approximating the counter state to be corrected and the counter states of the respectively significant adjacent counting points. <IMAGE>
